■ High-dose dexamethasone increases soluble P-selectin and von Willebrand factor (vWF) levels inhealthy men, according to researchers from Austriaand the UK. Their crossover study involved ninehealthy male volunteers who each received IVdexamethasone 0.04 mg/kg and 1 mg/kg (high dose),and placebo, twice daily for 2 days each. There was a6-day washout period between phases. Theresearchers found that levels of vWF were significantlyincreased from baseline at 24 and 48 hours followingthe administration of high-dose dexamethasone.Plasma levels of sP-selectin only showed significantincreases from baseline 48 hours after theadministration of high-dose dexamethasone. Theresearchers suggest that the probable mechanism forthe increase in vWF levels was dexamethasone-induced up-regulation of vWF-mRNA.Jilma B, et al.
